恒星团簇形成的物理和模式:观测

The physics and modes of star cluster formation: observations

Charles J. Lada

摘要:

星团诞生于寒冷的尘埃分子云中,最年轻的星团不同程度地嵌入尘埃暗分子物质中。这样的嵌入式集群可以被认为是原集群系统。最深埋的例子是如此严重地被灰尘掩盖,以至于它们只能在红外波长下可见。这些嵌入的原星团构成了最近的实验室,可以直接进行团簇形成和早期演化的物理过程的天文学研究。我回顾了目前的经验知识有关嵌入式集群系统和讨论的影响,了解他们的形成和随后的演变产生绑定星团。

英文摘要:

Stellar clusters are born in cold and dusty molecular clouds and the youngest clusters are embedded to various degrees in dusty dark molecular material. Such embedded clusters can be considered protocluster systems. The most deeply buried examples are so heavily obscured by dust that they are only visible at infrared wavelengths. These embedded protoclusters constitute the nearest laboratories for direct astronomical investigation of the physical processes of cluster formation and early evolution. I review the present state of empirical knowledge concerning embedded cluster systems and discuss the implications for understanding their formation and subsequent evolution to produce bound stellar clusters.
